本研究在探討Ba-Nd-Ti-Pb-Sr-Ca-Zn-Al-Si-O玻璃的緻密行為、結晶行為與材料性質間的關係。由研究結果顯示:此玻璃系統的緻密行為控制機制是玻璃的黏滯性流動。主要結晶相為鈣鈦礦結構的(Ba,Sr,Pb)TiO3,α-Al2O3、Ba2ZnSi2O7和PbTi3O7結晶。
由結晶潛伏期得到(Ba,Sr,Pb)TiO3比Ba2ZnSi2O7和PbTi3O7早形成。而後Ba2ZnSi2O7和PbTi3O7同時消失,且(Ba,Sr,Pb)TiO3隨之增加。判定Ba2ZnSi2O7和PbTi3O7反應形成(Ba,Sr,Pb)TiO3。
此玻璃系統結晶與緻密間的關係為:達到緻密前結晶產生則無法緻密,反之則系統可達緻密。
介電性質與鈣鈦礦結構的(Ba,Sr,Pb)TiO3含量有關,介電常數會隨(Ba,Sr,Pb)TiO3增加而上升。
